SLIP-SHACKLE.

Application filed December 22, 1913, Serial No. 808,209. Renewed March30, 1915.

To all whom it may concern:

Be it known that I, BERNHARD Sorrtir'rn, a subject of'the Grand Duke ofOldenburg, residing at Hasbergen, in the Grand Duchy of Oldenburg,German Empire, have invented certain new and useful Improvements inSlip-Shackles, of which the following is a specification.

This invention relates to a slip shackle, the construction of which isimproved by the addition of an angle lever to the free arm of which acurved lever is hinged, which is guided 0n the end of the hook by meansof a pin of the hook engaging with a slot of the lever so that, when theangle lever is lowered the cable is slowly lifted so that it can slipoff the shackle. The improved slip hook is fork-shaped and the free armof the operating lever and the lifting lever for the cable are mountedbetween the two arms of the fork-shaped hook.

In the accompanying drawings the invention is shown by way of example.

Figure 1 is a side elevation of the slip shackle. Fig. 2-is a side viewof Fig. 1. Fig. 3 illustrates the operation of the slip shackle.

The slip shackle b is pivotally mounted in the well known manner. In theshaft of the slip hook a cross bolt 0 is mounted on which the anglelever d is pivoted. At the free end of this angle lever ol a curvedlever f is hinged the shape of which corresponds with the shape of thehook. The curved lever f has a slot 9 mounted on a cross bolt-7t securedin the front end of the hook I). If the lever d is lowered the cable 6is lifted by the curved lever 7 whereby the slipping of theSpecification of Letters Patent.

cable is considerably facilitated. The hook I) is preferably fork-shapedand the angle lever (Z and the curved lifting lever f are mountedbetween the arms of the forkshaped hook.

The slip shackle is not only designed to be used on ships but also onrailways or the like.

I claim 1. An improved slip shackle comprising in combination with theshackle hook proper, a cross bolt in the shaft of said hook, an anglelever pivotally mounted on said cross bolt, a curved lever correspondingin shape with the shape of the hook hingedly connected with one end ofthe angle lever and having a curved slot, a cross bolt fixed in the endof the hook for guiding said curved lever, substantially as describedand shown and for the purpose set forth.

2. An improved slip shackle comprising in combination a fork-shaped sliphook, a cross bolt in the shaft of said hook, an angle lever pivotallymounted on said cross bolt and situated between the arms of theforkshaped hook, a cross bolt in the front end of the hook, a curvedlever having a slot hingedly connected with the free end of said anglelever and guided on said front cross bolt, substantially as describedand shown and for the purpose set forth.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
